YATOMIZER.

SPECIFICATION forming part of Letters Patent No. 538,967, dated May "1', 1895. Application filed September 1, 1894- $erial No. 521i (N0 model) To aZZ whom it may concern.-

Be it known that I, WILLIAM HUGERSHOFF, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Atomizers, of which the following is a specification.

This invention has reference to certain improvements in the atomizer, for which Letters Patent were granted to me heretofore, No. 514,190, dated February 6, 1894, whereby the same is adapted for vaporizing oily and other heavy medicinal fluids and for returning the so-called waste back into the vessel; and the invention consists of an atomizer, which comprises a receiving-vessel for the liquid, a cap applied to the same, atubular head-piece inserted into the cap and provided with a detachable nozzle, a bulb connected with said head-piece, a block inserted into' said headpiece and provided with a conical atomizingnozzle, and with a supply-tube which extends into the liquid vessel, said supply-tube being arranged with grooves at its upper end within the block, and a valved opening in said block through which air is admitted to the bulb when the same expands, but which is closed when the bulb is compressed so that the air is forced along the grooves of the supply-tube through the discharge-orifice of the atomizing nozzle. The tubular head-piece is provided with an opening below its nozzle, so as to permit the ingress of air in case the outer nozzle should be entirely or partly closed during the application of the atomizer to the parts to be treated.

In the accompanying drawings, Figure 1 represents a side elevationof my improved atomizer. Fig. 2 is a vertical central section of the head-piece with the atomizing device in the same, drawn on a larger scale. Figs. 3 and 4 are horizontal sections drawn on a still larger scale and taken, respectively, on line 3 3 and at 4, Fig. 2; and Fig. 5 is a side elevation of the upper end of the supply-tube, also drawn on a larger scale.

Similar letters of reference indicate corresponding parts. I

Referring to the drawings, A represents the liquid-vessel into which the oily or other medicinal preparation to be. atomized is placed.

B is a cap, which is tightly fitted on the neck of the liquid-vessel A.

O is a tubular head-piece, which is screwed into the cap and which is provided with an opening in its base so as to communicate with the neck of the liquid-vessel A.

C is a detachable nozzle which is rounded off at its outside, so as to be readily inserted into the nose or other part to which the atomized spray is to be applied.

The nozzle 0' of the tubular head-piece can be removed so as to give access to the interior of the latter.

D is an elastic bulb, which is not provided with any valve, and which is attached to a socket D, the latter being connected by a tube D with the tubular head-piece O.

The interior of the head-piece O is either arranged with a shoulder e or it is slightly diminished in width so as to support a block E, which is provided with a central upwardlyextending conical atomizing-nozzle f. The block- E is tightly fitted to the interior of the head-piece O, and is provided with a central screw-threaded opening, into which is inserted the upper threaded end of a supply-tube F, which extends through the neck downward into the liquid-vessel A. The upper end of the supply-tube F is located below the central orifice of the atomizing-nozzle f and provided preferably at four equi-distant points with longitudinal grooves f, through which the compressed air that is forced by the bulb D into the head-piece C, is conducted into the interior cavity of the atomizing-nozzle f and through the orifice of the same into the headpiece. The suction through the tube F, which is created by the air passed along the sidegrooves'f of the same, draws up the liquid in the vessel A through the supply-tube, and the pressure of the air forces the liquid through the orifice of the atomizing vessel f so as to change the same into spray which is then conducted through the vessel of the tubular headpiece to the part to be treated. This atomizer besides acting by suction on the liquid, also acts to a certain extent by pressure; for the pressure of the air on the surface of the liquid assists in raising the same through the supply-tube F.

The condensed vapors, or so-called waste, are returned through a valved opening 9 in the block E into the lower part of the headpiece, and from the same into the liquid-ves- 7 to the bulb whenever the nozzle is closed by the parts to be treated. In this case, no air could pass in and consequentlythe bulb could not expand and would create an injurious suction on the parts. The small air-inlet aperture then supplies the required quantity of air to the bulb without exerting any injuris ous suction on the parts to be treated.

My improved atomizer is especially adapted for atoi'nizing oily and other heavy medicinal fluids, and for returning the condensed vapors or waste back into the liquid-vessel, said waste passing along the conical surface of the atomizingnozzle and being sucked inwardly through the valved opening in the block when the expansion of the bulb takes place, the waste being then returned for further use into the liquid-vessel, whereby a considerable saving in the medicinal preparation is obtained. By unscrewing the head-piece from the cap and removing the nozzle of the same, the interior block, with its supply-tube, maybe removed, the cleaning of all the parts facilitated and the same readily replaced in position for further use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In an atomizer, the combination of a liquid-vessel, a tubular head-piece applied to the neck of the vessel and provided with a detachable nozzle, a bulb connected with the headpiece, a block inserted in the head-piece and provided with an atomizing-nozzle and a valved opening, and a supply-tube screwed into the block and provided with longitudinal grooves or channels in the part screwed into said block, substantially as set forth.

2. In an atomizer, the combination, of a liquid-vessel, a tubular head-piece applied to the neck of the same, a detachable nozzle at the upper end of the head-piece, an elastic bulb connected with said head-piece, a block fitted to the interior of the head-piece and provided with an atomizing-nozzle and a valved opening, a supply-tube, inserted into the block and provided with longitudinal grooves, or channels, and an air-inlet aperture arranged in the head-piece intermediatelybetween the inte rior block and the detachable nozzle, so as to permit the air to enter into the bulb when the nozzle of the head-piece should be closed, substantially as set forth.

In testimonythat I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
